This video shows a active shooter situation at a Walmart. The shooter was a tweaker with a history of substance abuse and other mental problems. A CCW'er, who also happens to be a pastor, puts a stop to it. Before the pastor puts the tweaker down, he shouts commands to the tweaker to stop and put his gun down. The pastor shoots when the tweaker fails to comply. The pastor witnessed the tweaker shooting at random people in the Walmart. The guy was obviously an imminent deadly threat to everyone around him. To be honest, I'm not sure that I would have bothered to shout commands at the guy. If I see someone taking shots at random people, and I've got a clear shot, I could see myself just putting him down then and there. If I shout commands at him and wait to see if he will comply, I put myself at risk of getting shot. How would you respond?
